ROBERT E. PATTEN, OF BOlVDOINHAM, MAINE.

SNOW-SCRAPER.

SPECIFICATION forming part of Letters Patent No. 289,131, dated November27, 1883.

Application filed August 21. 1883. (No model.)

To alt whom it may concern: Be it known that 1, ROBERT E. PATTEN, acitizen of the United States, residing at Bow doinham, in the county ofSagadahoc and have invented certain new and useful Improvements inSnow-Scrapers, of which the following is a specification, referencebeing had therein to the accompanying drawings.

Myinvention relates to scrapers such as are used to remove snow from thesurface of the ice; and the object of my invention is to provide ascraper which can be handled by one man, instead of three, as those incommon use now require, and which may be easily drawn to any requireddistance after being loaded. I accomplish thisresult by means of thedevice shown in the accompanying drawings, in which- Figure 1 shows ashows a side view.

perspective view. Fig.2 Fig. 3 shows a longitudinal section throughthecenter.

A A are two sled-runners, united by the cross-bar B and the drawing-barC. These runners are built up to a considerable height forward, theforward portion being filled in E is a scraper, made in the form of abox having one end removed. The rear end of the scraper E sits on thecross-bar B, and the pin P, fixed in the edge of the scraper, preventsit from sliding backward. On the lower edge of the scraper is securedthe shoe or cutter L, made of metal or other suitable material'. The boxE contains a sliding bottom, 6, which is arranged to slide backwarduntil stopped by the pegs It. This bottom 6 rests on the cross-piece K,which is attached to the bottom of the'boX-scraper E, and on the bar J,which is attached to the middle of cross-piece Kand extends backward,resting on the cross-bar B. The cross-piece e is joined to the rear ofthe sliding bottom a by means of cleats,and a space is left between itand the bottom large enough to insert a handspike.

On the outside of each sled-runner are the stanchions D D, and restingin bearings on the tops of these stanchions is the. shaft F, near eachend of which is a drum or pulley, G. Around these drums are wound ropesor chains, the lower ends of which are secured.

to the forward end of the box-scraper E. v

The lever I, secured to the end of shaft F by a pivot, extends backward,so that the end itself without manipulation.

may be placed cross-bar B. The ropes H H are so arranged thatwhen theend of lever I rests under the cross-bar B the end of the box-scraper Ewill be raised clear from the ice.

' When the scraper is to be used, the end of lever I is taken from underthe end of crossbar B and the forward part of the scraper falls to theice, as shown by dotted lines, Fig. 2. As the scraper is drawn forward,it fills The high runners increase the capacity of the scraper so longas it is left down. When the load is to be removed to a distance, thelever I is forced down and caught under the end of cross-bar B,thusraising the scraper from the ice and bringing the load on the tworunners, in which position it may be moved easily to any distance. Whenthe load is to be dumped, a handspike is inserted between the bar 6' andthe sliding bottom e and the horses started ahead. The bottom is thuswithdrawn, and

the load falls through. The stops R prevent the bottom from slidingentirely out. The load is dumped in a better manner than by theordinaryscraper, being smoothly depositedon the ground and not heaped in a pile.

My device is capable of being used as a horse-sled as well as a scraper.

It will be seen that my scraper may be easily managed by the man whodrives the horses, whereas the scraper now in common use requires thelabor of three men.

I claim- 1. The snow-scraper composed of runners A A, with theircross-bar B, combined with i the box-scraper E, having sliding bottom 6,and the hoisting apparatus consisting of lever I, shaft F, pulleys G G,and ropes H H, substantially as described. i

2. In a'snow-soraper, the runners A A,

under the projecting end of combined with the box-scraper E, with itssliding bottom 6, and with its rear end resting on cross-bars B, itsforward end being raised and lowered by lever I, substantially as shownand described. 3. In a snow-scraper, the runners A A, combined with thebox-scraper E, the forward end of which is raised and lowered,substantially as shown and set forth,

In testimony whereof I affix my signature in presence of two witnesses.
